All through the canals of Amsterdam are these long tour boats. They hold about 60 people and run all day from 10am to about midnight. We had them going by our houseboat a lot but it was fun to see the people, not intrusive.
Just a sample of how Amsterdamers use their bike. Sometimes the whole family was on one bike. Many times we saw people riding on the back, and they also have bikes with big boxes on the front to hold up to 3 kids. And nobody wears helmets! You don't see younger children riding their bikes out on the busy streets. The youngest we saw were teens.
